Linear Equations and Graphs

What is the slope of the line shown in the graph?

• The slope of the line can be calculated by finding the change in y divided by the change in x between any two points on the line.

• The slope of the line is undefined

• The slope of the line is equal to the y-intercept

• The slope of the line is always 0

Determine the y-intercept of the line in the graph.

• The y-intercept is -1

• The y-intercept is 0

• The y-intercept is 1

• The correct answer cannot be determined without the specific graph or equation of the line.

Write the equation of the line with a slope of 2 and a y-intercept of 4.

• y = 4x - 2

• y = 2x - 4

• y = 2x + 4

• y = 4x + 2

Graph the linear equation y = 3x + 2.

• Graph the linear equation y = 3x + 2 by plotting the x-intercept at (2, 0) and using the slope of 3 to find another point on the line.

• Graph the linear equation y = 3x - 2 by plotting the y-intercept at (0, -2) and using the slope of 3 to find another point on the line.

• Graph the linear equation y = 3x + 2 by plotting the y-intercept at (0, 2) and using the slope of 3 to find another point on the line.

• Graph the linear equation y = 3x + 2 by plotting the y-intercept at (0, 2) and using the slope of -3 to find another point on the line.
